Now what???

Now what???
This will be a long read sorry.
On labor day weekend I was headed to Minnesota from Ohio. Few hundred miles into my trip I developed a noise. It seemed like a ping so I did an autotune but it didn't help. Noise seemed to get louder by Chicago but I wasn't about to stop in Chicago so I kept going to Rockford. Found the HD dealer about 1:30 PM on Saturday afternoon of a holiday weekend. They test drove it and agreed with me that the noise now sounded like it was coming from the primary. They got me right in and tore down the primary and low and behold found the compensator was bad. At about 40k miles I knew it was worn out so I said go ahead and change it. They buttoned her back up and took it for a ride. Noise still there. It was now about 4:00 and the shop was closing. 4 mechanics, about 100 years experience and they couldn't agree where the noise was coming from. They were pointing in different directions. Top of the engine, primary, bottom of engine, left side, right side. Don't know what they would tear apart but could start tearing down on Tuesday. Rolled me outside and said sorry. Well, I continued as far as Madison Wisc and got a room. U-hauled home on Sunday.
I still believe the noise is in the primary so I opened it up and found my chain loose (I know. Kinda strange). The tensioner looked worn strangely only on the back of it not the front. Put in a Hayden m6. Noise still there.
Took it to my mechanic who thought the noise was from the cam chest so I tore it down. One guy in Rockford thought it was a lifter roller chirping too. Discovered some unusual wear on the tensioners. One almost looked melted. Changed them and opened the oil pump. Oil pump was badly gouged from something going through there. Replaced it with the SE cam plate and pump. Found one lifter roller seemed a little suspicious so I changed them all. Rinsed everything out best I could. This freakin' noise is still there.
If you are still reading this, thanks for sticking in there. The noise was described as a chirp. It seems to be in the primary to me but others have disagreed. It isn't a steady noise but rather a pulsing noise. It is there with the clutch in or out, in gear or neutral. Seems to come on about 1700 RPM all the way up. I have spent a small fortune changing worn components but none has eliminated my noise. Riding a 2008 FLHTC with Woods 6-6 cams, a little extra compression ratio with a welded crank with 40k miles since the initial rebuild at 10K.
Any thoughts or ideas? I don't know what to do next. Can't keep shotgunning this noise. Maybe it is time to ride it to destruction.
Any help or thoughts would be appreciated.

Mechanically any time I have had the phantom chirp like that it has always come down to a bearing. I don't know much about the internals on motorcycle engines (only because I haven't rebuilt one myself, knowing they are similar in design compared to an auto). Since you said it has a different cam I would start there (cam bearing?) I think, at least pull and inspect.

Sorry to hear about your dilemma. I have also heard some odd noises here and there. I don't know if I'm paranoid from reading these damn forums or is there really a slight tick once in a while. This is my first Harley so I don't know what to expect when it comes to longevity. Some guys never have problems and some seem to have the worst of luck. It honestly puts a damper on my riding. All these what ifs takes the damn fun out of it.

Yeah. I carry tools too. If it was just a carburetor, I could rebuild it on the road. I was 600 miles from home with a noise from the primary or the engine. I don't have the ability to rebuild either on the road. I do almost all of my own work and I do know how this machine works and still I can't pinpoint my noise. About 5 mechanics have listened to it and evidently none has been right about what is making this noise. I don't know where to turn now. Probably going to have to put it away for the winter broken. This sucks. Kegel Harley customer service was excellent but they couldn't find the noise. They got me right in and had the compensator off in about a half hour.

Yargh. The dreaded "chirp." Quite possibly my least favorite of all infernal noises. God knows I've chased a bunch of them over the years. Most of them have ended up being exhaust related, and the worst part is that they "carry" and often sound like they're coming from anywhere but the exhaust. Some that come quickly to mind are:
1. Very slight exhaust leaks at the cylinder head will chirp sometimes.
2. A loose or broken hose clamp on a heat shield will cause the heat shield to chirp.
3. I've had the rubber muffler hangers on baggers chirp when they get old and the rubber dries up and hardens. I chased one of these for over a year on my own bike one time and about drove myself the rest of the way insane in the process. It sounded like it was coming from the front rocker box to myself and several others. Just for grins, spray a little WD40 on the rubber muffler hangers and see if it stops. I know it sounds crazy, but it doesn't cost anything.
5. I've seen more than a few blown head gaskets that would chirp as compression escaped to atmosphere.
6. I've had broken fairing brackets chirp and those noises also tend to carry to other parts of the bike.
Best of luck. I hope it ends up being something minor.
